A bi-sexual slave's training intensifies as his mistress, a dominant and sadistic woman, pushes him to his limits. She forces him to watch as she teases and pleasures herself with a strap-on, grunting and panting, "You wish you could have this, don't you? You want to be the one fucking me." The humiliated slave, desperate for her touch, begs for her to use him, to let him taste her and her toys, but she only laughs, "Not yet, slave. You have so much more to learn."
